Short for precious, it's basically a group that consists of bestfriends. Mostly females, we have our own "language" we sound like grandma's talking to little babies at times. We all love eachother, we all understand eachother, we all have this "connection" type thing. You can't explane "us", it's just impossible. Pweshes laugh at everything, and anything. If you want to be a pwesh you have to prove to us that you are pwesh worthy, you have to be like us.
